Aeonium haworthii (Pinwheel) - A durable winter growing freely branching succulent shrub from Tenerife in the Canary Islands that can grow up to 24 inches tall with and equal spread. On its many branches are borne 3 to 4 inch wide rosettes of bluish-green leaves that are keeled on the lower surface and often tinged red along the ciliate margins. The flowers, which appear in late spring, rise above the foliage in a branched inflorescence and are very pale yellow to nearly white that are sometimes tinged pink. Plant in full sun to light shade along coast but requires light to full shade in hot inland locations. Likes a well-drained soil and tolerates little to no summer irrigation. Hardy to 25°F. This is long lived and tough enough that fine rounded specimens are often found in older gardens and neglected sites. It is listed as a good plant for near the beach, on steep and rocky slopes, and as an understory plant for Eucalyptus. Because of these traits it is often traded around succulent gardeners though it is not commonly grown in nurseries. The species received the Royal Horticultural Society's Award of Garden Merit in 1993
